Thousands of tubes and bottles of Savlon have been taken off shelves after animal rights activists claimed to have poisoned them.
High street shops, including Boots and Superdrug, acted after a hardline group claimed to have tampered with more than 250 items containing the antiseptic.
The Animal Rights Militia did not say how they had been damaged but it
recently claimed to have injected bleach into products in France.
An internet message said they chose Savlon because its Swiss-based manufacturer, Novartis, is believed to be among the clients of HLS.
The message warned: "We don't want to kill living beings but the side-effects and the inevitable hospital stay will give people an idea of what Novartis pays for inside Huntingdon Life Sciences."
